H&R race springs on 15" Si wheels. What size tires?

I've got my eyes set on the H&R race springs for my 99 Civic Si ( 2.5" front / 2.2" rear ). I plan on running the oem Si wheels for awhile and if I do go aftermarket, i'll keep the 15" size wheel and probably still run a 45mm offset. 42mm at the most.

With that said, I want to go 205/50/15 but I'm a little worried about rubbing. I know I will be just fine with 195/50/15 but that's a little smaller than I would like to run or will the stock 195/55/15's be just fine?

I've rubbed in the past on my eclipse GS-T and I ended up ditching some very expensive wheels and getting a 2nd set of tires so I really don't want to run into that again.

Thanks for the help guys! If anyone has anything similar to this setup, I'd love to hear about it.
